The longest non-chemical word in the english language, Pneumonoultramicroscopicsilicovolcanoconiosis refers to the inflamation of the linings of the lungs due to microscopic silica ash inhaled after a volcanic eruption
the longest word, period, is the chemical name for titin, though this is disputed as an english word because it is a chemical name. pneumonoultramicroscopicslicovolcanoconiosis, however, is a medical condition, and, therefore, is english.
